title: Gamma knife radiosurgery for other primary intra-axial tumors.
abstract: We report the usefulness of gamma knife radiosurgery for hemangioblastomas, hemangiopericytomas, germ cell tumors and pineal parenchymal tumors, and primary central nervous system lymphoma (PCNSL). In hemangioblastomas, small solid tumors can be treated very effectively. Hemangiopericytomas are still difficult to control due to their aggressiveness and metastasis to other organs. However, radiosurgery is a useful alternative to repeat craniotomy for recurrence. Radiosurgery is a reasonable option to control residual and recurrent germ cell tumors and pineoblastomas. Although the prognosis is poor for PCNSL patients, gamma knife radiosurgery, even with a relatively low tumor margin dose, is an effective treatment for controlling PCNSL.
